Off and Running is a 1991 American film starring singer and actress Cyndi Lauper. She stars as a mermaid-themed lounge singer who gets involved with a caring but troubled man. Because of his involvement with horse racing and breeding (and consequent mafia ties) he is murdered in front of her, and she goes on the lam to escape his killers. On the way she takes on the company of a professional golfer and a rebellious pre-teen boy and together they attempt to unravel the mystery behind her slain lover's past. The film was not widely distributed and coasted into notability mainly because of Lauper's involvement. It is generally available on VHS for less than a dollar. The movie fared far better in other countries where Lauper's popularity has sustained. In Germany and Japan it was packaged as "Moon Over Miami".

Cyd Morse is an actress, but her biggest role so far is as a recurrent guest on "Miami Vice". She earns her living with underwater dancing at the bar of the Eden Rock Hotel in Miami Beach. There she's approached by ex-jockey Woody; they start dating and kind-of fall in love. However it's a short luck: one evening he's brutally beaten to death in his hotel room. Cyd's a witness and gets hold of a key Woody had around his neck. She's got to flee from the murderer. Due to an accident she meets golfer Jack Connett. He can't resist her charme and helps her on the search for the lock to the key and the flight from the murderer. Written by Tom Zoerner
